The trailer also shows intimate shots of Beyonce, 31, on vacation, in her bedroom with no makeup and rehearsing. The film includes "extensive first-person footage, some of it shot by Beyonce on her laptop, in which she reflects on the realities of celebrity, the refuge she finds onstage and the transcendent joy of becoming a mother last year," according to HBO's website.

The documentary, for which Beyonce also acted as executive producer, is set to air on HBO Feb. 16.
